Senior Platform Engineer (DBaaS)

Rumble is the Freedom-First technology platform. We proudly offer a video platform, cloud services, advertising solutions, and a non-custodial cryptocurrency wallet.Rumble Cloud is building a DBaaS platform that makes reliable, high-performance databases available to our internal teams and customers without the usual operational friction. As a Senior Platform Engineer (DBaaS), you’ll own the Kubernetes-based platform that runs our managed database workloads on OpenStack, focusing on orchestration, reliability, automation, and security rather than deep engine-specific tuning. This is first and foremost a Kubernetes and cloud platform role. You’ll design and operate DBaaS as a multi-tenant, stateful service: making sure clusters are healthy, databases are highly available, storage and networking are robust, and the platform can scale quickly as adoption grows. You’ll partner closely with database specialists for engine-level decisions, but your core impact is in how you provision, harden, monitor, and evolve the infrastructure that powers the service. You’ll collaborate with Rumble Cloud engineering, SRE, and database architecture teams to take DBaaS from initial hardening through launch and into scale-out: defining SLIs/SLOs, building automation and runbooks, integrating with OpenStack services, and serving as a senior escalation point when platform issues impact customers. If you enjoy running Kubernetes in production, working on mission-critical infrastructure, and building platforms that other teams depend on every day, this role is for you. Responsibilities Own and operate the Kubernetes platform that powers DBaaS, including cluster provisioning, upgrades, capacity planning, and day-to-day reliability. Run relational databases (e.g., PostgreSQL, MySQL, MariaDB) as managed stateful workloads on Kubernetes using operators, StatefulSets, and persistent storage, with a focus on HA, backup/restore, and security. Integrate DBaaS with the underlying OpenStack infrastructure (Nova, Cinder, Neutron), ensuring networking, storage, and compute resources are configured correctly for multi-tenant database workloads. Design and implement automation and infrastructure-as-code for the platform using tools such as Terraform, Ansible, and Python/Bash, covering provisioning, configuration, upgrades, and lifecycle management. Build and maintain observability for DBaaS using Prometheus, Grafana, and related tools, including metrics, logs, alerts, and dashboards that surface health and performance of both Kubernetes and database workloads. Develop and document runbooks, SRE practices, and incident response procedures for DBaaS, and participate in on-call rotations as a senior escalation point. Work with database architects and application teams to define SLIs/SLOs, capacity and performance expectations, and safe change-management processes for database schemas and platform upgrades. Implement and enforce security best practices across the platform, includin...
